Title:
圧電式リニアアクチュエータ、圧電駆動バルブ及び流量制御装置
Document Type and Number:
Japanese Patent JP6799859
Kind Code:
B2
Abstract:
A piezoelectric linear actuator comprising a laminated piezoelectric actuator having a cylindrical shape; a lower support member supporting the laminated piezoelectric actuator and extending laterally to the left and right of the laminated piezoelectric actuator; a pair of displacement transfer members extending along the left and right sides of the laminated piezoelectric actuator, respectively, to slidably intersect the lower support member and transferring displacement due to the piezoelectric effect of the laminated piezoelectric actuator; and an output part locked to the pair of displacement transfer members below the lower support member and coupling lower end portions of the displacement transfer members, wherein the pair of displacement transfer members are formed to have a width dimension that is the same or substantially the same as the width dimension of the laminated piezoelectric actuator.
